Cov ntsiab lus ntawm cov tshuab kws dhos tshuab hlau tsim yog raws li nram no: Ua ntej, cov khoom ntim tsim yuav tsum ua kom tau raws li kev siv thiab kev ua tau zoo ntawm qhov khoom, thiab yuav tsum tau muab kho kom yooj yim thiab kho tau; ces nws yuav tsum yog txoj hauv kev txhim kho kev siv cov hlau ntaub ntawv thiab txo cov ntau yam thiab kev qhia ntawm cov ntaub ntawv. Nws yog ib qho ua tau kom txo tau cov khoom siv, siv cov khoom pheej yig thaum qhov ua tau, thiab ua rau tej yam tsis zoo thiab tsawg li tsawg tau; ces tus qauv tsim yuav tsum yooj yim rau hauv cov duab thiab tsim nyog hauv tus qauv, uas yog siv rau kev simplification ntawm pwm. Tus qauv simplifies cov naj npawb ntawm cov txheej txheem, uas yog, siv qhov tsawg tshaj plaws thiab qhov kev nyuaj stamping kom tiav qhov kev ua tiav ntawm tag nrho ib feem, thiab yog qhov ua rau lub lag luam stamping, pab txhawb lub koom haum ntawm mechanized thiab automated qhuav, thiaj li yuav nce zog tsim tau.
Yuav ua li cas ua cov hlau tshuab dhos ua ntej, ua ntej kom tau txais cov khoom seem, los saib cov ntug ntawm txoj kab, siv lub tshuab raws ntug kev xaim cais cov khoom seem thiab cov chaw tsis muaj dab tsi, tom qab kev sib cais zoo, raws li tus neeg thov yuav raug thwj thim tawm Ncauj los yog khoov, ua kom zoo, thiab thaum kawg zoo lawm. Tam sim no, cov khoom siv moulded yuav tau txau nrog cov xim xeb los yog xuas tes xuas, xaws npauj npaim, uas yog muaj peev xwm ua tau zoo dua qhov corrosion tsis kam ntawm nws cov khoom. , thiab muaj ib qho kev zoo nkauj
